The Nokia Lumia 900 has now been made official and will be an AT&T exclusive to begin with. The LTE handset has a 4.3-inch ClearBlack AMOLED display and the same sleek polycarbonate unibody sported by the Lumia 800.

The Lumia 900 also packs an 8-megapixel camera with a 28mm wide-angle lens and a 1.4GHz processor. This latest addition to the Lumia range also has a more powerful battery than the Lumia 800 as well as a front facing camera for video calling.

The LTE connectivity and premium functions have made Nokia peg this handset as the first Windows Phone designed specifically for the US market.

No official release dates have been confirmed for the US and we will have to wait and see when a European version will become available.
